I am trying to select an appropriate W-beam and channel cap for a runway beam that is to support an under running bridge crane. The channel cap is to be on top of the W-beam. I am using the AISC ASD code and I am having problems with what value to use for "bf" in formula F1-2. Would "bf" be...
ahunt,
Thanks for the link. Can you give any input on the difference between the formulas used on the website you provided and those in section K.1.2 and K.1.3 of the AISC ASD spec.
Thanks,

Can anyone lead me to a reference that gives allowable stresses on an I-beam flange due to wheel loading from a bridge crane end truck.
Thanks in advance for any help.

Does anyone know if there is a reference that gives relative cost differences (per pound) between structural tubing shapes and rolled shapes such as W-beams and channels and plate.
Thanks in advance for any help.

I uncovered something that I may have overlooked in past design calculations. The question comes up when analyzing the stresses on a tapered padeye (with a long base to hole dimension) or on a tapered beam. The tapered member is loaded perpendicular to the longitudinal axis of the member. For...
Can anyone tell me why the AISC code has both the slenderness check and the check for the loading case of combined bending and axial? Dosen't satisfying the equations H1-1, H1-2 & H1-3 act as a check on buckling. If so then why does the slenderness check need to be done?
The slenderness check...
My company is considering the purchase of Multiframe 3-D with code AISC checking software to do some minor 3-D frame analysis. I have reviewed their demo and it seems to do what we need. Does anyone know if there are other packages that do about the same thing as Multiframe for about the same...
Can anyone tell me how to calulate torsional stress on an I-beam section? I have read texts that state that the shear stress of each individual section is based on the the sum of torsional resistances of each individual section of the beam. Is this the standard way of computing the shear...
I was wondering if anyone could tell me what is the standard for calculation the maximum stress on the outer fiber of a beam that is loaded laterally such that it has a beanding stress and a shear stress. My current understanding is that if the beam is short then the bending and shear stresses...
